Turmeric (Curcuma domestica Val.) has many health benefits and can be used in herbal medicine as well as traditional herbal drink. Turmeric can also be used as a natural dye in food. Turmeric is very perishables in a fresh state, thus drying process is needed to extend its shelf life. An environmentally friendly drying using Solar Tunnel Dryer (STD) is one of the techniques that is interestingly developed. The purpose of this study was to determine the effect of steam blanching at different times (3, 5, and 10 minutes) and soaking using a 0.05% citric acid for 5 minutes on the physicochemical and microbiological qualities of turmeric dried by STD. Measurements were conducted to analyze water content, water activity, curcumin content, antioxidant activity, pH, water activity, color intensity, and total fungi. The results showed that steam blanching and immersion using a 0.05% citric acid for 5 minutes could reduce the drying time when compared to that of control. While 5 minutes of steam blanching with immersion in the 0.05% citric acid for 5 minutes could produce a high antioxidant activity which was 80.30 ± 0.89 (% inhibition) and it had the lowest total fungi which were 3.33 ± 5.00%

Oil palm is one of the major plantation commodity that earns foreign exchange. The expansion of oil palm plantation potentially gives not only economic benefits, but also the environmental problems. Therefore, the economic and environmental impacts of oil palm plantation expansion need to be assessed. This study uses revenue analysis to estimate the economic benefits, descriptive analysis to identify environmental impacts, and to estimate external costs using replacement cost and cost of illness. In this research, expansion is defined as the conversion of a part of or whole rubber plantation to oil palm plantation. The expansion resulted in farmers turning some or all of rubber gardens into palm oil plantations that resulted in an increase in revenues of 40.52%. In addition to the on-farm sector, farmers benefit from off-farm (24.46%) and non-farm (25.61%), bringing the total increase of farmers' income by 33.42%. Based on community perceptions of environmental impacts due to oil palm plantation expansion in the form of reduced quantity of groundwater, water pollution, and decreased animal population. The environmental impact of crude palm oil (CPO) factories is to produce liquid waste from palm oil processing that raises external costs for the community in the form of the replacement cost of clean water and the cost of illness

Crop-livestock was a concept of zero waste system and good for the environment. This study aimed to determine the effect of farming characteristics on farmer incomes Mesa Village, Teon Nila Serua Sub District, Central Maluku District. Type of farming characteristics consisted of two groups, namely farmers who have integrated coconut, cocoa and cattle, and farmers who relied on the plantation sector. The data used was primary data obtained by the method of interviews and questionnaires. Data were analyzed using the Mann-Whitney test statistic. The results obtained that the income of farmers who perform the integration of cattle, coconuts, and cocoa did not differ significantly with farmers' income derived from the coconut and cocoa. This was because maintenance of cattle still traditionally and there has been no development of farm products. Increased productivity in the crop-livestock system could be done by making a communal cage, cultivation of fodder crops, and dissemination of technology

Pangalengan is located in the high land region with an altitude of 1.000-1.420 m above sea level, which has an average temperature of 17.80 ± 1.46 0C and humidity of 63.99 ± 2.74%. These environmental conditions will affect the physiological values of dairy cattle, especially during the lactation period. However, information about the physiological parameters of lactating cows in this area is not available. This study used 20 lactating dairy cows, and physiological values were measured in the morning, midday, and afternoon. The ranges of heart rate, respiration rate, and rectal temperature of dairy cows during lactation period were 59.82-72.02 times/min, 26.01-36.69 times/min, and 37.32-38.36 0C, respectively. The range of hemoglobin, hematocrit, erythrocytes, and leukocytes of lactating dairy cows was 8.29-9.51 g/dl, 24.52-29.70%, 6.10-8.18 million/µl, and 6.220-10.600 cells/µl, respectively. The range of differential leukocyte of lactating dairy cows were lymphocyte 32.64-63.14%, neutrophils 28.34-53.24%, monocytes 0.41-4.85%, eosinophils 1.58-15.78%, and basophils 0%, respectively. The range of a ratio of N/L of lactating dairy cows was 0.41-1.63. This study concludes that lactating dairy cows maintained under mild Pangalengan climatic conditions still show physiological values within the normal range
